Per Webster....a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease.
Did you get the covid shots? Are you immune?
Thank you for posting the definition if what a vaccine is. The vaccine does everything as described.
